BORING-TOOL R DETENIT-TERRIER FOR OIL-WELLS, s06.

SPECIFICATION forming part of Letters Patent No. 299,632, dated June 3, 1884.

Application filed March 5, 1884. (N0 model.)

To all whom it may concern.-

Be it known that I, ALBERT FAUOK, a citizen of the United States,residing at Kleczany, Galicia, Empire of Austria-Hungary, have invented certain new and. useful Improvements in Boring-Tools or Dete'nt-Terriers for Oil-VVells, &c., of which the following is a specification.

This invention relates to an improved automatic boring-instrument of the class known under the name of detent-terriers, which instrument is specially adapted for boring'to greater depth for water, petroleum, and other purposes; and the invention consists of a guideframe, a slotted guide-sleeve, a boring-tool secured to a detent-piece, and an automatically-working detent and releasing device, which will be more fully set forth hereinafter.

In the accompanying drawings, Figures 1 and 2 represent two different side views of my improved automatic boring-tool, and Figs. 3 and 4 are details of the detent device.

Similar letters of reference indicate corresponding parts.

The boring-tool a carries at its lower end the bit I),- and is connected to the detentpiece a by means of two keys, a a. The detent-piece c is guided in its movement by the longitudinally-slotted sleeve d. This arrangement secures a great solidity of the apparatus, and enables the different parts of the same to be readily taken apart. The sleeve cl carries at its upper end a rod, e, of square section, which is guided by the head f of a guideframe, 9 g. The upper end of the rod 0 is provided with ascrew for connection with a socket of the boring-rod or steel-wire rope. This connection is well known and not represented in the drawings. The guide-frame g g is composed of two side rails, which are fixed to the head f, and of a strong ring, i, that connects the lower part of the side rails. The guideframe r g serves as a guide for the boringtool a, and as a base for the automatic detent device. The detent-piece c is provided near its upper end with an upper transverse and slightly-oscillating crOsspiece, c, and with a lower fixed cross-piece, c (Shownin detail in Figs. 3 and 4..) Both cross-pieces c c are guided by the longitudinal slots at of the sleeve d, the upper cross-piece, 0, being made of greater length than the lower cross-piece, 0 The upper cross-piece, 0., turns by center pivots in steel bearings h h, which are secured into transverse holes of the detent-piece c by conically-tapering keys h it. As the cross-piece c has to be secured to the detent piece after it has been inserted into the sleeve (1, the keys h are introduced through suitable holes at the lower end of the sleeve, and retained in place by the sleeve itself. The upper ends d of the guide-slots d are inclined and made wider than theslots (1 so as to form a seat, (1 for the upper cross-piece, c.. The head f of the sleeve (1 is provided with fixed downwardlyextending rails K K, the lower ends of which are inclined, as shown in Fig. 1.

When the boring-tool is at work, the frame 9 g is resting upon the bottom of the borehole. Upon the descent of the boring-rod, the upper inclined ends (1 of the guide-slots d of the sleeve d engage the upper crosspiece, 0, and turn the same, so that on the ascent of the boring -rod the cross -piece 0 is taken along by the seat (1 of the sleeve (1. When the boring-bit during its ascent has reached nearly its highest point, the inclined ends of the fixed rails K K push the upper cross-piece, 0, off its seat, so that the boringtool and its detent-piece are dropped.

The guide-frame g 9 should be longer than the boring-tool (inclusive of the suspended piece) by the length of the stroke of the bit minus about six centimeters, so that the guideframe is taken along a short distance after the detent-piece has fallen, so as to facilitate the turning of the tool.

The apparatus works as well without water and without rebound of the walking-beam.

The above-described detent apparatus secures a reliable working of the boring-tool, which is best effected by a stroke of 1.25 meter and with twenty to thirty blows per minute.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination of a guide frame, 9 5 having fixed rails K K, inclined at the ends, a slotted sleeve, d, having a square rod, 6, a detent-piece, c, carrying the boring-tool a, the detent-piece 0 having a longer oscillating crosspiece, 0, and a fixed lower cross piece, c'", the cross-piece 0 being engaged by the rails K and automatically disengaged by the same during the ascent of the boring-tool, substantially as set forth.

2. The combination of a guide-frame, g 5

having fixed rails K K, with inclined ends, a sleeve d, having a fixed rod, 0, and longitudinal guide-slots (I with inclined upper ends d and seats (1, a detent-piece, c, carrying the boring-tool a, and having a transverse longer oscillating cross-piece, 0, and a fixed shorter cross-piece, 0 substantially as and for the purpose set forth.

In detent-terriers, the combination of the detent-piece 0, having an oscillating cross piece, 0, with rails K, having inclined ends,

said rails being fixed to the head of the guideframe 9 g, substantially as described.

4. The combination of the boring-tool a with the detent-piece c by means of a double key, a a, which facilitates the taking apart of the diiferent parts of the apparatus, substantially as described.

5. In detent-terriers, a guide-frame composed of side rails, a head, and a connecting ring at the lower part of the side rails, sub stantially as set forth.

6. In detent-terriers, the detentpieee c, having a fixed lower cross-piece, c, and an upper longer cross-piece, 0, that is centrally pivoted to transverse steel bearings 71/ h, secured by wcdgekeys h h, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

ALBERT FAUCK.
